setCompactionThreshold

Sets the threshold at which an oplog will become compactable. Until it reaches
this threshold the oplog will not be compacted.
The threshold is a percentage in the range 0..100.
When the amount of garbage in an oplog exceeds this percentage then when a compaction
is done this garbage will be cleaned up freeing up disk space. Garbage is created by
entry destroys, entry updates, and region destroys.

Parameters:

compactionThreshold - the threshold percentage at which an oplog is compactable

setQueueSize

Sets the maximum number of operations that can be asynchronously queued.
Once this many pending async operations have been queued async ops will
begin blocking until some of the queued ops have been flushed to disk.

setDiskDirs

Sets the directories to which this disk store's data is written. If multiple
directories are used, GemFire will attempt to distribute the data evenly
amongst them.
The size of each directory will be set to the default of DEFAULT_DISK_DIR_SIZE.
